Participants: Healthy, overweight older adults 
Dosage: 6 mg/day of spermidine supplemented orally for 13 weeks

Oxford scientists find that spermidine, a naturally occurring molecule that declines with age, rejuvenates aging immune cells and improves vaccine protection in older adults. 


Study conducted at the University of Oxford in England. 

Immunity

Japanese scientists have found that reducing NAD+ (nicotinamide adenine dinucleotide) transport into mitochondria within the fat tissue of mice induces metabolic dysregulation and obesity. 

Duke University scientists have successfully induced new neuronal connections in the brains of mice, leading to improvements in social interaction and stress resilience.
